Hitless stacking failover provides automatic failover from the Active Controller to the Standby
Controller without resetting any of the units in the stack and with sub-second or no packet loss to
hitless stacking-supported services and protocols.

Enabling hitless failover
To enable hitless failover, enter the following command at the Global CONFIG level of the CLI:
PowerConnect(config)#hitless-failover enable
The command takes effect immediately. Hitless switchover is allowed, and in the event of a failover,
the standby controller will take over the active role without reloading the stack.
Syntax: [no] hitless-failover enable
Use the no form of the command to disable hitless stacking once it has been enabled.
